About the DXY (U.S. Dollar Index)
The DXY measures the value of the U.S. dollar against a basket of six major currencies: euro (57.6% weight), Japanese yen (13.6%), British pound (11.9%), Canadian dollar (9.1%), Swedish krona (4.2%), and Swiss franc (3.6%). It's a single number that captures the dollar's overall strength or weakness. Today's 103.55 means the dollar is roughly 3.5% above the baseline level set in March 1973 when the index started at 100.
What moves the DXY
Interest rate differentials are the dominant driver — when U.S. rates rise faster than rates in the basket countries, the DXY climbs. Inflation differentials, growth expectations, and global risk-off flows (the dollar is the world's reserve currency, so it strengthens during global stress) also matter. The euro's heavy weight means EUR/USD moves dominate DXY movement in normal markets.
Reading today's level
The DXY hit a multi-decade peak at 114.78 in September 2022 when the Fed was hiking aggressively into a slowing global economy. It has since drifted lower as the Fed-vs-rest-of-world rate gap narrowed. Today's 103.55 is in the middle of the post-2014 range. The all-time high — 164.72 in February 1985 — preceded the Plaza Accord, when major economies coordinated to weaken the dollar.

Frequently asked
What this number means, and what it doesn't.
The DXY basket was set in 1973 and rarely updated. China, India, and other emerging markets weren't major trading partners then. The currencies in the basket represent ~60% of U.S. trade in 1973. The Federal Reserve publishes alternative dollar indexes (Broad Trade-Weighted Dollar Index) that include yuan and other emerging-market currencies and weight them by trade share.
A strong dollar makes imports cheaper (good for consumers, bad for U.S. exporters), foreign travel cheaper for Americans, and dollar-denominated debt harder for foreigners to service. A weak dollar does the opposite. The 2022 dollar surge pushed import prices down and helped cool U.S. inflation.

164.72 on February 25, 1985 — the Reagan-era strong-dollar peak. Following weeks led to the Plaza Accord (Sep 1985) where the G5 agreed to weaken the dollar through coordinated central-bank action. The DXY then fell 50% over two years.
